When you turn the coarse adjustment knob of a microscope, it moves the stage up or down to bring the specimen into rough focus. This adjustment is used to quickly change the focus of the image.
The part of the microscope that moves the stage up and down is called the coarse focus knob or adjustment knob. This allows you to bring the specimen into focus by adjusting the distance between the objective lens and the stage.
The coarse adjustment knob brings objects into rapid focus by quickly moving the stage up or down. It is used first to focus roughly on the specimen before fine-tuning with the fine adjustment knob.
The stage on a microscope is typically moved using coarse and fine adjustment knobs located on the mechanical stage assembly. These knobs allow the user to move the stage up and down or side to side to adjust the position of the specimen for viewing.
The stage of the microscope, where the specimen is placed, does not move when the adjustment knob is turned. Instead, the focus of the microscope is adjusted by moving the stage up and down by use of the adjustment knob.
The "base" supports the microscope. The "arm" holds the eyepiece, bodytube, fine and coarse adjustment knob, nosepiece, and the high and low power objective which connects to the "base. "
The coarse adjustment is used to focus in on the specimen. It accomplishes this by moving the stage or the upper part of the microscope.

When turning the coarse adjustment on a microscope upwards or downwards, the distance between the tube and the stage changes. This changes the detail of what you can see of the specimen you are examining.

For course focusing the primary stage is used.
I believe it's the coarse adjustment.

The fine adjustment knob on a microscope allows for precise focusing of the image at high magnification by making small adjustments to the distance between the objective lens and the specimen. It is used after rough focusing with the coarse adjustment knob to bring the image into sharp detail.
First of all, one should never call it high power, it is morecommonly called the "high objective", yet that is not what this question is asking. To answer the question: You use the fine adjustment knob. This knob should be located near the coarse adjustment knob, on the opposite side of the microscope (at the same height as the coarse adjustment knob), or even as a separate knob protruding from the coarse adjustment knob. The fine adjustment knob is smaller in size. You should never, ever use the coarse adjustment knob under the high objective, you could scratch the microscope slide, cover slip, high objective lens, or in a worst case scenario break the high objective lens.
Because if you use coarse adjustment, the body tube of the microscope (the part that moves up and down when you turn the knobs) will hit the microscope slide and cause the slide to break/crack. It moves the tube very quickly . You also run the risk of damaging the high power lens when it hits the slide. The fine adjustment only moves the tube a teeny tiny bit and very slowly so you don't have a great of a risk of damaging the slide or lens. The fine adjustment also helps to focus slowly so you don't miss the object you're trying to see.
The part of a telescope were you adjust the size of the lens
